Sen. Elizabeth Warren, D-Mass., accused President Trump of “playing politics” with the lives of residents of Puerto Rico who are facing limited access to food, water and medicine in the wake of Hurricane Maria.

“PR is in CRISIS. US citizens are dying. Millions of people need their govt’s help. Stop playing politics with their lives, @realDonaldTrump,” Warren tweeted.

Warren also said she spoke with San Juan Mayor Carmen Yulin Cruz and praised her work with recovery efforts.

“I just got off the phone with Mayor @CarmenYulinCruz. I told her to keep up her heroic work & leadership on behalf of Puerto Rico,” she said in a second tweet.
